I am trying to parse a CSV file as an input for my process.
I used the FilePoller to detect any changes, made in the .csv file. The poller is connected to the ParseData Activity which is referenced by the DataFormat Ressource, where I am defining the structure of my data. The output of ParseData is used in the RenderXML activity to create an xml string.
I am facing the issue, that I am not able to loop through each line in the CSV file to parse it to an XML document structure.
Do you have a resolution, how to implement this?
Please find the "Demo" process attached to this post.

Thank you in advance

Select both the RenderXml and WriteFile activities. You can do that by clicking one, and then holding the Shift button while you click on the second.
Right-click over the selected activities, and select Create Group > Iterate. This will create an Iterate Scope around the two selected activities.
Click on the Properties panel and select the output of the ParseData activity as the Variable List through which you would like to iterate.
I hope this helps!
As per my understanding you are getting repeated element in Parse Data Output and these repeated element you want to map to render xml schema . Which is not allowed until and unless in schema you have element to which you want to map is of repeated type. If that element is of repeated type then map element from the right side to left side and select for each option. Then for every element in Parse data it will map to schema element.
Hope Your doubt get resolved.

I have a nifi flow that takes in .csv files and partitions each into multiple records with each csv column value added as an attribute.
At one point in the flow, I'd like to collect the value of one attribute from each record that passes though. There could be from 0 to n collected. Once I have the list, it'll be emailed out.
I'm trying to avoid me (or someone else) getting bombed with emails if there are 200+ bad records in a file. So if I could collect for a fixed period of time or until another attribute (filename) changes, that would be great.
I've tried merge content and record. I even tried replace text to replace the content w/ just the attribute value I want to save and merging those, and a slew of other things.
Is there a simple way to do this in nifi?
Have you tried UpdateAttribute with a new attribute of type array. When each flowfile passes the this processor you could continue to update the value of this attribute by appending a new value to the array, attribute.
However, as #daggett pointed out, it will be helpful if you can provide the input and expected output.
Hi i have found some video and text on how to do this but they dont help with this task.
I know how to get one values but not extract a table.
I want this to get exported into a database if possible or a Excel. But i cant figure it out.
I have even tryed change the "Change reading opption"
I tryed to "data scraping" but the program just say
"This controler does not support data extraction"
And it can't be more of a table then this.
I have heard that it cant be because the structure of the PDF is bad.
Still isn't there more ways of doing this.
Unfortunately, there is no activity in UiPath to read tables directly from PDFs. (As of today.) That was the bad news. The good news is that you can get to the contents of the PDF. Either you get the data (as flat text) directly with UiPath.PDF.Activities.ReadPDFText or you have to use OCR.
#kwoxer provided a wonderful link for explanations on this topic.
I have already been able to extract data from tables contained in a PDF document. At that time, I was lucky: ReadPDFText extracted everything. The table elements were separated by tabs ("\t"). And the table header contained a word that did not appear elsewhere in the document.
Just as an idea, I proceeded like this:
Extract text from the PDF document with UiPath.PDF.Activities.ReadPDFText.
Create an array, where the elements are the lines in the document. (Split using Environment.NewLine and option StringSplitOptions.RemoveEmptyEntries)
Go through lines in a loop (ForEach) until the table header is found. (StartsWith or Contains etc.)
The next row belongs to the table as long as it contains a tab. (Otherwise the table is over.)
Split current row by tab and store it in an array: The elements of the array are the individual cells of the row.
I hope, this idea help.
How to read an excel sheet and put the cell value within different text fields through UiPath?
I have a excel sheet as follows:
I have read the excel contents and to iterate over the contents later I have stored the contents in a Output Data Table as follows:
Read Range - Output:
DataTable: CVdatatable
Output Data Table
DataTable: CVdatatable
Text: opCVdatatable
Screenshot:
Finally, I want to read the text opCVdatatable in a iteration and write them into text fields. So in the desired Input fileds I mentioned opCVdatatable or opCVdatatable+ "[k(enter)]" as required.
Screenshot:
But UiPath seems to start from the begining of the Output Data Table whenever I called for opCVdatatable.
Inshort, each desired Input fileds are iteratively getting filled up by all the data with the data stored in the Output Data Table.
Can someone help me out please?
My first recommendation is to use Workbook: Read range activity to read data from Excel because it is quicker, works in the background, and does not require excel to be installed on the system.
Start your sequence like this (note the add headers property is not checked):
You do not need to use Output Data Table because this activity outputs a string containing all row items. What you want to do instead is to access the items in the data table and output each one as a string in your type into, e.g., CVDatatable.Rows(0).Item(0).ToString, like so:
You mention you want to read the text opCVdatatable in an iteration and write them into text fields. This is a little bit more complex, but i'll give you an example. You can use a For Each Row activity and loop through each row in CVDatatable, setting the index property if required. See below:
The challenge is to get the selector correct here and make it dynamic, so that it targets a different text field per iteration. The selector for the type into activity will depend on the system you are targeting, but here is an example:
And the selector for this:
Also, here is a working XAML file for you to test.
Hope this helps.

Here's a different, more general approach. Instead of including the target in the process itself, the Excel would be modified to include parts of a selector:
Note that column B now contains an identifier, and this ID depends on the application you will be working with. For example, here's my sample app looks like. As you can see, the first text box has an id of 585, the second one is 586, and so on (note that you can work with any kind of identifier including the control's name if exposed to UiPath):
Now, instead of adding multiple Type Into elements to your workflow, you would add just a single one, loop over each of the datatable's row, and then create a dynamic selector:
In my case the selector for the Type Into activity looks as follows:
"<wnd cls='#32770' title='General' /><wnd ctrlid='" + row(1).ToString() + "' />"
This will allow you to maintain the process from the Excel sheet alone - if there's a new field that needs to be mapped, just add it to your sheet. No changes to the Workflow are required.
In a uft-api test I have a select data component that returns the query results. The results comeback in an array and I'm trying to figure out how to write the results back to the test's data pane, either excel or local table.
You can use GetDataSource Class of UFT API ,
it will work like this lets say you imported excel from FlightSampleData.xls, and named it as FlightSampleData, you have <input> sheet, accessing the sheet will be like below:
GetDataSource("FlightSampleData!input).Set(ROW,ColumnName,yourValue);
GetDataSource("FlightSampleData!input).Get(ROW,ColumnName);
I recommend you go to help section of UFT , there are many valuable documents that we thought we never had. all the object reference is out there .
this.Dbfetch10.OutputProperties.GetElementsByTagName("EMP_NAME").item(0).InnerText;
Note :-
EMP_NAME - exact field name in database
Dbfetch10- appropriate stepname of the SelectData
I want to know which is best strategy to aboard the following problem in Talend:
I need to load data from a set of delimited files that are stored in a directory with names like (SAMPLE1.DAT, SAMPLE2.DAT, ... , SAMPLEX.DAT)
The target will be a table in a MySQL database
I have to load all data at once because after this task I need to work with all records in the same table
I'm a bit confused because I don't know if it possible in Talend. I was seeing the tFileInputDelimited component but I didn't find the way to solve it.
Thanks
To read several files from one directory, you would use the tFileList component. It allows you to specify a directory and a file name pattern. All files in the directory matching the pattern will be processed, one after the other.
You need to use an "Iterate" link from the tFileList component to those components that describe what you want to do with each file. In your case, you would start with a tFileInputDelimited component (read the file) and connect the main output of that to a tMysqlOutput component. The MySQL component will, by default, just append the data to an existing table, so that should get you the result you want.
In the tFileInputDelimited component, you would not use a fixed filename, but a variable filename which is set by the tFileList component for each iteration (your loop variable, so to speak of). The name of that loop variable can be seen in the "outline" view in the studio, usually in the bottom left corner.
You would use components tFileInputDelimited into tMap (optional) into tmysqlOutput
Step 1 : configure some components like this, except you will use the delimited file input:
Step 2 : configure the component settings for the delimited file, click the disk for the wizard :
Step 3 : configure your database by right clicking on Db Connection under metadata, then following wizard:
Step 4 : Right click on each component and choose Row > Main > drag to next step in flow.
Step 5 : Open your tMap and map the columns from the file schema to the database schema.
Step 6 : Run the job, it should work if you have followed all the wizard, if there are errors just hover over the red component and it usually describes errors pretty well. You will see as the job runs how many records it has transferred.
Step 7 : after you have made it that far, create a tfiledelimited output with the same schema as the input, right click on the input choose Row > Rejects and drag that to the new delimited output, this is where and records that are rejected by the tmap will be sent.
